Ideal Temperature for Patchouli
Signs of Cold Stress in Patchouli
Symptoms
Patchouli thrives in warmth and cannot withstand cold. It grows optimally when temperatures exceed 65℉. In winter, maintain temperatures above 60℉. If temperatures drop below 50℉, leaves may lose color. Following frost damage, leaves progressively turn brown or black, exhibiting wilting and drooping.
Solutions
Remove frost-damaged sections. Promptly relocate indoors to a warm area for protection. Position the plant near a south-facing window for sufficient light. Furthermore, keep it away from heating or AC vents to prevent excessive air dryness.
Signs of Heat Stress in Patchouli
Symptoms
In summer, Patchouli should be kept below 80℉. When temperatures surpass 85℉, leaf color fades, and the plant becomes more prone to sunburn.
Solutions
Prune off sunburned and desiccated portions. Move the plant to a spot offering shade from intense midday and afternoon sun. Water the plant in the morning and evening to maintain soil moisture.
